Shavers was not the hardest puncher IMO, and nowhere near it. His so called "power" stemmed off of from quotes from fighters that were not knocked out by him. He has a surprisingly weak resume for someone who's considered to be "the hardest puncher ever". It might seem hard to deny him given so many quotes about him regarding his power, but think about it, the first and the most popular quote about him originated from a washed up, old and brain damaged Ali. Given his self promotive nature, Ali hyped up his win from Earnie in order to make his struggle in the fight look like a much bigger achievement than it really was by exaggerating Shavers' power. The next opponents Shavers fought (and lost to) said the same about him. Their quotes just like Ali's had the intention of boosting their own wins from Shavers given his false reputation as being an absurdly powerful puncher (which was fabricated by the still incredibly popular Ali). In other words, they hyped Shavers up just to boost their own wins. This is just my hypothetical explanation. What's your opinions ?
